Okay, I've enabled intremap=no_x2apic_optout on the host kernel and didn't see much of a change in performance. I feel I should mention that the qemu process on the host consumes about 8-30% CPU (as shown in top) when the guest (Windows 10) task manager shows <1.0% cpu utilization. More often than not, it is >15%. Is this normal?
Maybe try to look at the Interrupt, disk and network statistics on the first and second tab of the Windows 8/10 Task Manager and see if there is any correlation with the extra host CPU use? I know the details there are a bit meager compared to what might be available with lower level Windows tools, but at least it's easy.
